Abstract
The utility model provides a kind of filtering cover, comprise lid main body, described lid main body comprise the main body cover that can form a filter space and bottom described filter space and surrounding arrange and be fixed on the filter membrane on described main body cover, described main body cover comprise setting section and the lower setting section be positioned at below described upper setting section and be connected described upper and lower setting section for strengthening described main body cover intensity and limiting the connection guard member that described filter membrane too expands outside described filter space; The periphery of described upper setting section extends outward rest edge.The utility model result is simple, easy to operate, only need pour filtered fluid into filtering cover, and treat that it filters completely, overall structure is firm, to the fixation of filter membrane, can ensure filter effect.
Description
Technical field
The utility model belongs to separating substances purification art, particularly a kind of filtering cover.
Background technology
In the prior art, a lot of to the filter method of solution, common filtration conventional method is with filter tunnel and filter paper, filters, or utilize vacuum apparatus to filter by glass bar drainage; For the fine filtering that ask for something is higher, need by miillpore filter and syringe etc., even need to utilize centrifuge to be separated.These filter methods, operate all cumbersome, need in use to prepare in advance, such as, filter paper is attached to inner wall of hopper, assembled etc. by vacuum plant.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of filtering cover, conveniently carries out filter operation, only filtering cover need be placed on the mouth of pipe of receiving vessel, and structure is simple, practical.
Above-mentioned purpose of the present utility model is achieved by the following technical programs:
A kind of filtering cover, it comprises lid main body, described lid main body comprise the main body cover that can form a filter space and bottom described filter space and surrounding arrange and be fixed on the filter membrane on described main body cover, described main body cover comprise setting section and the lower setting section be positioned at below described upper setting section and be connected described upper and lower setting section for strengthening described main body cover intensity and limiting the connection guard member that described filter membrane too expands outside described filter space; The periphery of described upper setting section extends outward rest edge.
Technique scheme; by adopting the main body cover with the mouth of pipe adaptation of receiving vessel; simply filtering cover is placed in receiving vessel oral area in use; band filter liquide is poured in filter space; by setting section and connection guard member, roughly can shape to filter membrane, can not under the effect of filter liquide during filtration; to the surrounding excessive compression of filter space, ensure the service life of film.Filter membrane can select the filter membrane without aperture as required.
Preferred as such scheme, the described connection guard member connecting rod that to be the some width be connected between described upper and lower setting section be between 0.1cm-0.3cm.
The width of connecting rod is too small, does not have the effect of restriction filter membrane overdistension, wide, can affect filter effect.
Preferred as such scheme, described connecting rod comprises inside connecting rod and outer tie rod, and described filter membrane, through being fixed described inside and outside connecting rod, is strengthened supporting and protective effect.
Preferred as such scheme, described upper and lower setting section is circle, and the diameter of described upper setting section is greater than the diameter of described lower setting section, increases the area of filter membrane, improves filter effect.
Preferred as such scheme, described rest edge is provided with by its outstanding Handheld Division formed, local, periphery, handled easily.
The utility model has following technique effect:
The utility model result is simple, easy to operate, only need pour filtered fluid into filtering cover, and treat that it filters completely, overall structure is firm, to the fixation of filter membrane, can ensure filter effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in further detail.
This specific embodiment is only to preferred embodiment of the present utility model; but protection domain of the present utility model not limited by embodiment; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Embodiment 1:
As shown in Figure 1, a kind of filtering cover, it comprises lid main body, lid main body comprise the main body cover 1 that can form a filter space and bottom filter space and surrounding arrange and be fixed on the filter membrane 2 on main body cover, main body cover 1 comprise the upper setting section 11 of circle and the lower setting section 12 of the circle be positioned at below upper setting section 11 and be connected upper and lower setting section 11,12 for strengthening main body cover intensity and limiting the connection guard member 13 that filter membrane 2 too expands outside filter space; The diameter of upper setting section 11 is greater than the diameter of lower setting section 12.The periphery of upper setting section 11 extends outward rest edge 111, and rest edge 111 is provided with by its outstanding Handheld Division formed, local, periphery.。Connect guard member 13 for being connected to the some width connecting rod between 0.1cm-0.3cm between upper and lower setting section 11,12, the present embodiment selects width to be the connecting rod of 0.2cm, and the radical of connecting rod is determined according to the size of filtering cover, and the present embodiment is 3.
Embodiment 2:
A kind of filtering cover, it comprises lid main body, lid main body comprise the main body cover 1 that can form a filter space and bottom filter space and surrounding arrange and be fixed on the filter membrane 2 on main body cover, main body cover 1 comprise the upper setting section 11 of circle and the lower setting section 12 of the circle be positioned at below upper setting section 11 and be connected upper and lower setting section 11,12 for strengthening main body cover intensity and limiting the connection guard member 13 that filter membrane 2 too expands outside filter space; The diameter of upper setting section 11 is greater than the diameter of lower setting section 12.The periphery of upper setting section 11 extends outward rest edge 111, and rest edge 111 is provided with by its outstanding Handheld Division formed, local, periphery.。Connect guard member 13 for being connected to the some width connecting rod between 0.1cm-0.3cm between upper and lower setting section 11,12, the present embodiment selects width to be the connecting rod of 0.2cm, and the radical of connecting rod is determined according to the size of filtering cover, and the present embodiment is 3.Wherein, connecting rod can be divided into inside connecting rod and outer tie rod again, and filter membrane is through being fixed inside and outside connecting rod.
The utility model state is at work as follows: first filtering cover is placed on the container mouth of pipe containing filtered fluid, the liquid that need filter again pours filtering cover into, the liquid that need filter is by Action of Gravity Field down seepage, treat that it completes filtration, remove filtering cover, this filtering cover can be disposable, also can reuse, and determines according to the needs of actual filtration.
